FLOOR-DRESSING MACHINE.

T 0 all whom it may concern:

Be it known that I, WALTER S. HAVEN, doctor of medicine, a citizen ofthe United States, residing at Racine, county of Racine, State ofWisconsin, have invented certain new and useful Improvements in Floor-Dressing Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and usethesame.

This invention relates to certain improvements in floor dressing,surfacing or polishing machines; and the objects and nature of myinvention t ill be readily understood by those skilled in the art in thelight of the following explanation of the construction shown in theaccompanying drawings to illustrate what I now consider the preferredembodiment of my invention from among other variations and arrangementswithin the scope of the following claims.

The invention consists in certain novel features in construction and inarrangements and combinations of parts as more fully and particularlyset forth hereinafter.

Referring to the accompanying drawingsz-Figure 1, is a perspective viewof one form of my floor dressing machine. Fig. 2, is a longitudinalvertical section through a floor surfacing machine showing the structureof 1, with the exception that the floor engaging tool is arranged on thesane side of the fulcrum as the lever instead of on the opposite side asin Fig. 1. Fig. 3, is a cross sectional view of the structure of 1. Fig.4, is a perspective view of a modification. Fig. 5, is a detailperspective of a portion of the movable carrier, the loose fulcrumsleeve thereon, and a form of scraper tool carried by the sleeve. Fig.6, is a detail perspective of a modification. Fig. 7 is a detailperspective showing a polishing or finishing pad which can be removablyapplied to the hand lever instead of the scraper shown by certain otherviews of the drawings.

The machine shown comprises means for maintaining one or more tracks orrunways above and approximately parallel with the floor to be dressed, acarrier movable along said tracks, and a hand lever mounted or fulcrumedon or to said carrier and provided with a floor surfacing tool of anysuitable or desirable nature or construction, whereby the operatorthrough the medium of the lever, reciprocates the tool and applies thesame to Specification of Letters Patent.

the floor with the desired pressure. The track or tracks form thebacking, support or means which enables the operator to attain the leveraction on the tool in pressing the same to the floor. The track ortracks is or are essential to the broad feature of my invention, wherebythe leverage of the tool against the floor is attained, but the meansfor fixing the tracks relates to the specific features of my invention.

If preferred, the tracks might form a part of a frame work so arrangedthat the means employed to fix or maintain the tracks would consist of apart of the frame on which the operator could stand so that his weightwould hold the tracks in place. Under this specific arrangement, myinvention comprises a horizontally disposed frame provided with a fixedor movable platform adapted to rest on the floor to be dressed anddesigned to be manually shifted along or over any desired portion of thefloor as the work of dressing the surface thereon progresses. A suitabletrack or runway is attached to and projects from this frame orconstitutes a part thereof, and this track is arranged parallel with anda suitable distance above the floor surface to be dressed. Areciprocating carrier is confined to the track and carries a floordressing tool or element and a hand lever whereby the carrier and toolcan be reciprocated and whereby the tool is held to the floor surfacewith the desired amount of pressure. The operator usually stands on theplatform so that his weight will hold the machine in position on thefloor and against slipping or sliding during the dressing operation,although other means might be provided for this purpose. The hand leverusually extends upwardly and rearwardly so as to be readily accessibleto the operator as he stands behind the machine or on the platformthereof, whereby the lever can be em ployed as a handle to reciprocatethe carrier provided with the floor dressing element and at the sametime as a lever to hold said element down to its work.

In the specific examples illustrated in the drawings, I provide a strongrectangular or oblong open frame work constructed of any suitablematerial, and at one end carrying the frame or platform 1, on which theoperator can stand. This platform can be of any suitable or desirableconstruction and of a size to receive one or both feet of the operator.I usually mount the frame on any suitable legs or other floor supports2, adapted to rest on the floor and hold the frame in a horizontalposition and elevated from the surface of the floor although I do notwish to so limit my invention. If so desired certain or all of thesesupports 2, can be provided with friction or biting surfaces 20, toengage the surface of the floor and aid in holding the machine inposition on the floor and against slipping during the reciprocation ofthe dressing tool.

In the specific examples illustrated, the spaced parallel side bars 3,of the frame form tracks or runways, and are rigidly spaced and securedtogether by the frame ends or cross bars 4, with the end legs 2,depending from the frame corners.

The platform 1, is shown arranged across an end of the frame and mountedon the side bars thereof. I show the platform mounted on the frame barsso as to be capable of being moved longitudinally thereof in case it isde sired to shift the position thereof for any reason, but do not wishto so limit my invention. I show each frame side composed of a pair ofspaced parallel bars 3, arranged one over the other and forming alongitudinal slide or runway, although I do not wish to so limit myinvention.

In the specific example illustrated, a reciprocating carrier 5, isarranged transversely of the frame between and confined to the sidesthereof to reciprocate longitudinally thereof. The carrier shownconsists of a strong cross bar 5, at its ends confined to said slidewaysby any suitable means. For instance, in Fig. 4, I show the bar 5, fixedto slides 6, confined to slide between or on the frame bars 3, while inF igs! 1, 2, and 3, I show the bar 5, carried by and forming the axle ofgrooved rollers 7, confined between the double frame sides to travellongitudinally thereof. A hand lever 8, is supported by said carrierwhich forms the lever fulcrum. The lever extends upwardly from thecarrier and toward the end of the frame provided with the platform. Theportion of the lever depending from the carrier is provided with anysuitable floor polishing, finishing or surfacing tool.

I usually form or provide the lever with a sleeve 9, mounted on thecarrier 5, and in all of the constructions shown, except theconstruction of Fig. 4, this sleeve is free to slide longitudinally ofand turn or oscillate axially on the carrier 5. This sleeve 9, coulesthe lever to the carrier and enables the ever to rock vertically on thecarrier as a fulcrum or center.

The inclined lower arm of the lever is usually formed by a socket 10,rigid with and projecting downwardly and radially from the sleeve 9 atan inclination to the floor, in connection with the shank 11 of thefloor en- 55 gaging tool fitted removably in the socket and secured byany suitable means such as set or clamping screw 12, so that the toolcan be removed for repair or sharpening or to permit application ofanother tool of a different form or character.

In Figs. 1, 2,3 and 5, I show scrapers of various forms consisting ofinclined flat blades 13, secured to shanks 11, removably fitted andsecured in the sockets 10, of the lever fulcrum sleeves or sockets 9.

In Fig. 6, I show the fulcrum sleeve 9, of the lever formed with a rigiddepending lug or arm 14, to whichshank 15 of scraper blade 13, isremovably clamped by U-shaped bolts 16.

In Fig. 7, I show a smoothing, surfacing, polishing or rubbing padconsisting of head 17, having the bottom rubbing surface 18, of anysuitable polishin or abrading material. This pad is removabIy secured tothe lever by a shank 19, clamped in socket 10. The shank being pivotallyjoined to head 17, by suitable means, such as eyes 20.

In Fig. 4, the lever sleeve 9, preferably oscillates on the carrier 5,but is held against longitudinal movement.

The socket 10, of the lever is shown removably receiving the shank of aforked head 21, forming the lower end of the lever and carrying a floorsurfacing or polishing tool in the form of an elongated horizontalrotating wheel or cylinder 22. Any suitable means can be provided forrotating said cylinder as the carrier is reciprocated by the lever, andby rocking the lever, the cylinder can be held to or raised from thefloor.

As a means which might be employed to positively rotate the cylinder, Ishow a toothed rack 23, secured longitudinally to one of the frame bars3. One end of the bar 5, carries a loose pinion 24, in mesh with therack, and this pinion 24, is fixed to a large gear 25, meshing with apinion 26, fixed on the end of cylinder 22.

In Fig. 2, I show the lower end of the lever extended rearwardly, sothat downward pressure on the handle end of the lever, moves the tool tothe floor, whereas in the other figures I show the lower end of thelever extended forwardly so that the tool is held to the floor by upwardpressure on the handle 1 end of the lever.

In all the structures shown, except that of Fig. 4, the lever is movablelaterally, by the sleeve 9, sliding longitudinally of bar 5, so that thetool can operate over an extended area of floor, before it becomesnecessary to shift the position of the frame to bring a fresh area offloor within the range of action of the tool.

If so desired the lever 3 can be formed, as shown by Fig. 6, with twoupwardly diverging handle ends 8, so that two operators zoo facing eachother can actuate the device. I

I do not wish to limit myself to the means shown for malntammg thereclprocatory carrier to reciprocation over the floor surface and tohold said carrier down to sustain the pressure of the lever when holdingthe tool to the floor surface, as various forms and ar rangements oftrack or guide way devices might be employed for this purpose, nor do Iwish to limit all features of my invention to the employment of the toolcontrolling lever as the manual means for reciprocating the carrier.

It is evident that various changes and modifications might be resortedto, that parts might be omitted and other parts added, without departingfrom the spirit and scope of my invention, and hence I do not wish tolimit myself to the exact constructions disclosed.
